I'm an adult and weigh like 135. My partner and I often sleep on it together and it's fine- really makes good use of my small bedroom. But after about 3 months it's started to wobble. The bolts that keep the bed together on the sides wiggle themselves loose (it's fine, they're really long bolts and the bed wouldn't have ever come apart). They need to be tightened every month or so if adults are going to be getting up and down every day. Otherwise I'm happy with it.
Great (but keep the Allen key nearby)
